这里有新鲜出炉的Python3 官方中文指南，程序狗速度看过来！
Python编程语言
Python 是一种面向对象、解释型计算机程序设计语言，由Guido van Rossum于1989年底发明，第一个公开发行版发行于1991年。Python语法简洁而清晰，具有丰富和强大的类库。它常被昵称为胶水语言，它能够把用其他语言制作的各种模块（尤其是C/C++）很轻松地联结在一起。
前言
本文主要介绍的是关于python 3用BeautifulSoup抓取div标签的方法示例，分享出来供大家参考学习，下面来看看详细的介绍：
示例代码：
# -*- coding:utf-8 -*-
#python 2.7
#XiaoDeng
#http://tieba.baidu.com/p/2460150866
#标签操作
from bs4 import BeautifulSoup
import urllib.request
import re
#如果是网址，可以用这个办法来读取网页
#html_doc = "http://tieba.baidu.com/p/2460150866"
#req = urllib.request.Request(html_doc)
#webpage = urllib.request.urlopen(req)
#html = webpage.read()
html="""
<html><head><title>The Dormouse's story</title></head>
<body>
<p class="title" name="dromouse"><b>The Dormouse's story</b></p>
<p class="story">Once upon a time there were three little sisters; and their names were
<a href="http://example.com/elsie" rel="external nofollow" class="sister" id="xiaodeng"><!-- Elsie --></a>,
<a href="http://example.com/lacie" rel="external nofollow" rel="external nofollow" class="sister" id="link2">Lacie</a> and

soup = BeautifulSoup(html, 'html.parser') #文档对象
